The principles of low-power energy conversion have been rooted in direct current (DC) to DC (DC-DC) power converters (such as buck converters, boost converters, buck-boost converters, switched capacitor converters, etc.). A buck converter uses non-linear circuits created by connecting passive components (such as inductors, capacitors, etc.) to switching devices (such as transistors, diodes, etc.). The buck converter can control such switching devices to reorganize the connections between an input source and an output load to adjust the input source (e.g., a voltage) to a desired output voltage, lower than the source voltage. Similarly, a boost converter converts a source voltage to a desired output voltage higher than the source voltage. A buck-boost converter can convert a source voltage to a desired output voltage higher or lower than the source voltage (e.g., depending on control of the switches). A switched capacitor converter is a voltage regulator that does not require an inductor. A switched capacitor converter uses capacitive energy storage and switching algorithms to deliver high efficiency voltage conversion from a source voltage to a desired output voltage.
